48 HEMIPTERA-HETEROPTERA. 
surrounding it very prominent, the outer one abruptly curved behind; the costal area with a single 
row of large areole; the sutural area unequally reticulated. 
Length 24-3, breadth 1-14 millim. 
Hab. Mexico, Atoyac (H. H. Smith), Orizaba (Bilimek, in Mus. Vind. Ces. ; 
H. H. Smith); Guatemaua, Zapote (Champion); Nicaragua, Chontales (Janson). 
Fourteen examples. Very like M. monotropidia, but with the membranous margins 
of the pronotum broader and extending inwards, the median nervure of the elytra more 
abruptly curved behind and also more prominent, usually with a short branch extending 
obliquely inwards at the point of curvature. WM. loricata, Dist., from Entre Rios, is 
another closely allied species ; but it differs from M/. c-nigrum in having the elytra longer, 
with the areole of the costal area very unequal in size, and the triangular posterior 
portion of the pronotum and the discoidal area of the elytra rather widely reticulated. 
One of the specimens from Orizaba is of a pale ochraceous colour, due to immaturity. 
An example from Atoyac is figured. 
An additional species of Tingitide has been sent to me for examination from the 
Vienna Museum since the preceding pages were in type ; it is as follows :— 
LEPTOSTYLA. 
9 (a). Leptostyla partita, n.sp. (Tab. IIT. fig. 26.) 
Elongate, narrow, widening behind; body black, the integument whitish and hyaline; the elytra with a. 
small spot on the discoidal area, a curved oblique fascia extending from the inner part of the sutural area 
to the costal margin near the tip, and the nervures beyond it fuscous, the other nervures pale testaceous ; 
the antenne testaceous, the basal joint and the apical half of the fourth joint black ; the legs testaceous. 
Head with three slender prominent spines; antenne elongate, slender, joint 1 about two and a half 
times as long as 2, 3 about three times the length of 4. Pronotum with moderately wide, raised, 
membranous margins, gradually converging forwards, with the anterior and hind angles rounded, the 
areole small and in two rows; hood short and small, considerably raised, projecting slightly in front ; 
the outer carine feebly, the median carina more strongly, foliaceous, the interspaces closely punctured ;. 
the triangular posterior portion membranous and closely reticulated. Elytra twice as long as the 
abdomen, constricted at the middle and widening beyond, the apices rounded; discoidal area narrow, not. 
reaching the middle, closely, reticulated ; subcostal area very narrow, biseriate ; costal area with two rows 
of rather large pentagonal areole at the middle, diminishing to one at the base and apex; sutural area 
very unequally reticulated, the areole becoming very large at the apex. Rostrum reaching the meso- 
metasternal suture. 
Length 23, breadth (of the elytra near the tip) 1 millim. 
Hab. Mexico, Pedregal (Bilimek, in Mus. Vind. Ces.). 
One example. Closely allied to Z. gracilenta, from Guatemala, from which it 
differs in having the elytra much longer and narrower, and more constricted at the 
middle, with the costal area not so wide and uniseriate only at the base, and the apical 
joint of the antennz partly testaceous. From the North-American L. oblonga (Say) it 
may be separated by the narrower and longer elytra, with the areole of the costa] area 
much less elongate.
